REXROTH EFC 3610 Series - Motor Parameter Auto-Tuning

Fig. 12-58: Slip frequency compensation
If the slip frequency compensation is excessively large, the motor
speed may exceed the synchronous speed.
Code Name Setting range Default Min. Attri.

By default, this parameter will be set automatically according to the basic motor
parameters. The value can be adjusted with the following equations:
● n

Motor parameter auto-tuning
Function description
With the configuration of motor nameplate parameters, the frequency converter
can run in V/f control. In addition, the following parameters are calculated auto-
matically based on the motor nameplate parameters:
